Abstract
Starfish oocytes were injected with mRNA for the serotonin 1c receptor or with rat brain poly A+ mRNA, incubated to allow expression of the membrane protein, then matured to eggs by addition of 1-methyladenine. Applying serotonin to these eggs caused cortical granule exocytosis like that occurring at fertilization. Because the serotonin 1c receptor specifically activates a G-protein, these results provide support for the hypothesis that sperm activate eggs by way of a receptor-G-protein interaction. The starfish oocyte may be a generally useful system for expression of exogenous mRNA for membrane proteins.
